Bias regulated rolling truck bed cover

ABSTRACT

A tonneau system that includes one or more tonneau sections and a retraction system. The retraction system has an adjuster shaft; a bias member; a drive roller in communication with the adjuster shaft; one or more lines connected to the one or more tonneau sections and/or to the drive roller; and an adjuster to adjust torque provided by the bias member. The bias member is connected to the adjuster shaft, the drive roller, or both.

FIELD

The present teachings relate to a truck bed cover that is a hinged tonneau system with a plurality of tonneau sections that are foldable relative to each other and specifically a truck bed cover that is connected to a cable, which regulates movement of the truck bed cover between an open position and a closed position.

BACKGROUND

Tonneau systems cover an open area of a vehicle and generally cover an open area of a pick-up truck (i.e., a bed). Multiple different types of tonneau systems are available, with some of the tonneau covers being solid and opening about a pivot, some folding upon themselves, and others rolling up. With the roll up type covers, as the cover begins to roll up an amount of force required to store the cover gradually decreases. In some instances, the cover may begin to extend to a storage position and the user may have to resist movement of the tonneau cover towards the storage position. Conversely, upon removal of the cover from the storage position, the user may have to exert a large amount of force and as the tonneau cover deploys an amount of force may gradually decrease. Further, in moving between a stored position and a deployed position the tonneau cover may not be fully supported by a portion that covers a tail gate and thus the tonneau cover may sag. A sag in the cover may require user assistance to guide the tonneau into a closed position. Finally, the tonneau covers, in a closed position, may prevent water from entering the bed of a vehicle. When water and debris land upon the tonneau cover, the water may pool upon the cover so that upon opening the cover some of the water may enter the bed of the vehicle.

Examples of tonneau systems are found in U.S. Pat. Nos. 4,889,381; 4,563,034; 4,786,099; 4,792,178; 5,251,950; all of which are expressly incorporated herein by reference for all purposes. It would be desirable to have a retraction system that both assists in storing a tonneau cover and deploying a tonneau cover. What is needed is a retraction system that maintains a substantially constant amount of force upon an entire closing movement, an entire opening movement, or both. It would be desirable to have one or more pulleys that adjust upon travel of the tonneau cover within a canister that stores the tonneau cover. What is needed is a connection system with one or more connectors that connect a tonneau cap to one or more tonneau sections. It would be desirable to have one or more tail supports that assist the tonneau cap with forming a connection with an end of a bed or a tailgate of a bed without needing user assistance to extend the tonneau cap over the end or tailgate. What is needed is a tonneau system with a plurality of drain features that assist in removing water from the tonneau system so that the bed remains dry.

The disclosures of all articles and references, including patent applications and publications, are incorporated by reference for all purposes. Other combinations are also possible as will be gleaned from the following claims, which are also hereby incorporated by reference into this written description.

The foldable tonneau system (tonneau system) functions to cover an open area and prevent fluid, debris, dirt, or a combination thereof form entering the open area (e.g., a bed of a pick-up truck, and hereinafter “bed”). The tonneau system may function to lock a bed so that items may be stored within the bed. The tonneau system may be collapsible so that items may be placed within the bed without interference from the tonneau system. The tonneau system may fold upon itself to expose the bed. The tonneau cover may roll up or roll into a canister that stores the tonneau cover of the tonneau system. The tonneau system may include one or more tonneau sections and preferably a plurality of tonneau sections.

The tonneau sections (i.e., section) function to connect together to create one contiguous surface. The tonneau sections may lock together. The tonneau sections may be longitudinally movable, rotationally movable, or both relative to other tonneau sections. The tonneau sections when in a closed position may prevent fluid, debris, dirt, or a combination thereof from entering a bed. The tonneau sections may be separate pieces. The one or more tonneau sections may be connected together to extend within a first plane. The one or more tonneau sections may extend along a first plane when the tonneau sections are in a closed position. The one or more tonneau sections may extend from the first plane and into the canister when the tonneau sections are moved into the stored position. The one or more tonneau sections may extend in a first plane and the line may extend in a second plane that is substantially parallel to the first plane. The tonneau sections may be connected together by a hinge, an outer covering, or both. The tonneau sections may be connected together by a cover that is flexible so that one tonneau section is movable relative to another tonneau section. The tonneau sections may be a plurality of sections that are flexible so that the tonneau sections may mirror the shape of the track.
